Java web導出word，文件名為中文，%E6%9D%90%E8%B4%A8%E5%8D%95亂碼

因為文件名為中文，導出時會有亂碼問題

原代碼：

 String fileName = "文件名.doc";  
 response.setHeader("Content-Disposition", "attachment;filename=".concat(String.valueOf(URLEncoder.encode(fileName, "UTF-8"))));  

 

修改為：

String uncod=URLDecoder.decode("文件名.doc","UTF-8");
String fileName = new String(uncod.getBytes("UTF-8"), "iso-8859-1");
response.setHeader("Content-Disposition", "attachment;filename=".concat(String.valueOf(fileName)));

導出中文名成功！
